Democratic presidential candidate Bernie Sanders is proposing a criminal justice overhaul that aims to cut the nation's prison population in half, end mandatory minimum sentencing, ban private prisons and legalize marijuana."We have a system that imprisons and destroys the lives of millions of people," Sanders told The Associated Press before the planned released of his proposal Sunday.

Sanders was promoting the plan during a weekend of campaigning in South Carolina, where the majority of the Democratic electorate is African American.
